He is the guy that is going to answer the phone when you call. He will be the one to recommend what prop to fly on your airplane. Warp Drive has come a long way since the days Dennis Souder shared with us, when Dennis would call Warp Drive and they would try to figure out what was going to work best on that particular application. They have the numbers now on most all applications, except some of the newer aircraft, and they will obtain figures for them ASAP. Warp has one of the best guarantees of the prop manufacturers - lifetime customer satisfaction. I called Darrell this morning to see if he would put white tips on my blades. Also to confirm the new polished prop hub will fit the 5" spinner. The last hub and spinner I got from them, the hub was slightly smaller than the spinner. This system did not work well in the pusher configuration. Now, that problem has been eliminated. Does the spinner improve performance in the pusher configuration? I don't know, but it does make the airplane look better. I got a chance to see the polished hub, spinner, and white tips at Oshkosh. They are an improvement on what I have now. With the new starter and slip clutch installed in my 912S, I anxiously await the arrival of my new prop. I flew the first 100 hours or so on the 912S with the 72" prop. It has been three years ago, but I still remember the kick in the butt those long blades made when I poured the coal to Miss P'fer.

(today is my Saturday) It was a Cessna 337 pushme/pullya twin, and I've rarely heard such a racket. Must be at full throttle, with the props on fine pitch, I guess.

I have been flying with a new GA instructor (working on finishing my GA ticket) and have been flying with the mentioned extra tail weight. We did power off stalls today. We found that in the 6 or so stall we did that the left wing would always drop off. Not too drastically, but a good 20 deg or so. Recovery was very easy, just let it nose down, gain airspeed with leveling wings, add a little power and level nose. Pretty uneventful. One thing that the instructor and I are both noticing is that we are flying most of the time with 30-50% left rudder to keep coordinated. My slip gauge may be slightly off, but I doubt by that much. There is not any rudder trim tab on the plane. Between 80% left rudder on fullpower takeoff and flying around at 30%+, it sounds like my plane could sure use a rudder tab. Being as inexperienced in the kolb as I am... I have no idea how to add one, how big of one to buy... if it is recommended at all etc. Any suggestions?

I have been flying dual with the 10-15 pounds on the tail both before and after I bought the plane. Stalls break slightly left, but the nose does drop right down. I do notice landing is far easier dual, but I have not tried dual without the weight. The previous owner has tried this and found that he would always be flying with full up trim, and still have to hold a good bit of back pressure on the stick. I will call TNK and ask a few questions and try and perform a weight and balance this weekend.

Thanks, Aaron - ________________________________ Message 9 _____________________________________ Time: 09:58:13 AM PST US From: Matt Dralle Subject: Kolb-List: [PLEASE READ] - Why Do I Have A Fund Raiser Each Year? --> Kolb-List message posted by: Matt Dralle Dear Listers, I was thinking that perhaps I should explain why I have a Fund Raiser and also take the opportunity to express why I think the List Services here provide a far better experience than the commercial equivalents. I use the List Fund Raiser each year to offset the costs involved with running a high performance email list site such as this one. With the annual support from the List members through the PBS-like Fund Raiser, I have found I can run the entire site without having to inflect any of the members with those annoying banner ads flashing up all the time trying to sell Toner Cartridge Refills or other garbage nobody wants or needs. From the comments I've received over the years regarding the Lists, the great majority of the members really appreciate the non-commercialism of my List systems and don't mind my 'go-team-go' banter once a year to encourage members to support the Lists. I believe that the Lists services that I provide here offer a great many benefits over the commercial equivalents in a number of ways. The first feature I believe to be particularly significant is that you *cannot* receive a computer v*rus from any of my Lists directly. I've been on a few other List servers and have been unfortunate enough to download infected files people have innocently or not-so-innocently included with their posts. This just can't happen with my Lists; each incoming message is filtered and attachments stripped off prior to posting. I provide a Photo and File Share feature that allows members to share files and bitmaps with other members and everyone can be assured that these files will be prescanned for any sort of v*rus before they are posted. Safe and simple. Also, with this photo and file sharing technique, the Archives don't get loaded up with a huge amounts of bitmap "data" that slows the Archive Search times. Another feature of this system is the extensive List Archives that are available for download, browsing, and searching. The Archives go all the way back to the very beginning of each List and with the super fast Search Engine, the huge size of the Archives is a non-issue in quickly finding the data you're looking for. Another feature of the Archives, in my opinion, is that they have been primarily stripped of all the useless email header data and all the other header garbage that seems to build up in a typical email thread. I have received an extremely positive response from Listers regarding the List Browse feature and the consensus is that the format and ease of use is outstanding. Members report that having the previous 7 days worth of messages on line for easy browsing and sorting is hugely beneficial. And again, as with the real time distribution of List email, the messages are stripped of all the unnecessary email headers and potentially dangerous v*ruses. I've been running email Lists and services under the matronics.com domain since about 1989 starting with RV-List and 30 guys who I knew and who where also building RVs. It has grown into over 40 different aviation-related Email Lists and an associated web site that receives over 10,000,000 hits each year!! Additionally, the List email system forwards well over 90,000,000 (yes, that 90 MILLION) email messages to subscribers each year! With all the dot.bombs these days, I think there's a lot of value in supporting a service that has gone the long haul and is still providing and improving a high quality service at a price that's nearly free. I have to admit running these Lists is a labor of love and I hope it shows in the quality of the experience that you receive when you get a List Email Message, Search the Archives, or use the List Browser. The Lists will be here for a long time to come. If you just want to lurk a while for free, that's great and I encourage you to do so. If you use, appreciate, and receive value from these Lists, then please support them during the Annual List Fund Raiser! ----------------------------------------------- The SSL Secure Web Site: http://www.matronics.com/contribution ----------------------------------------------- Thank you, Matt Dralle Email List Administrator ________________________________ Message 10 ____________________________________ Time: 10:37:24 AM PST US From: Richard Pike Subject: Re: Kolb-List: Aircraft Noise --> Kolb-List message posted by: Richard Pike Last year I tried a Supertrapp muffler on my Suzuki 650 and they are a good deal. It was a straight through glasspack with a stack of baffles that bolts to the end, and as you add baffles, you increase the surface area for the gas to exit through. Started out with just a couple, and it was quieter than stock, (which was quiet) and similar performance. Kept adding baffles and when I got enough, you could feel it quite noticeably, it had much better torque and pull. Adding more baffles made more noise, but no more performance, so I went back to the right number and have a very satisfying power-to-noise ratio. There are a variety of them on e-bay, I think anyone with a four stroke that wanted to cut their noise could get a light weight aluminum one and readily adapt it to their setup.

But as soon as you start to apply trim pulling the lever back, the springs begin to make themselves known with the stick neutral. See how that works for you.

I have had neighbors come up to me that are over a mile away and comment on how much quieter my airplane is now. They claimed that they could hear me wind up for take off in their house over a mile away. I used to have a muffled direct drive VW and it was terrible. I now have a unruffled reduction drive VW that is significantly quieter. I used to make radio calls at cruise power settings and I would get " aircraft broad casting all I hear is noise" . I had to throttle back to approach power settings to be able to use the radio. My 72 inch prop now rarely turns more than 2100 RPMs and I think it is still the biggest noise maker.

I want to know if this is a normal thing to do (adding tail weight for dual).. aaron i dont know anyone who has done this.... but i have considered it..... i just crunched some numbers and hope i have not tried to make it too simple and goofed in the process. lets assume that the cg of the airplane is at 20 inches behind the leading edge. to make the calculations easy let us move the datum to 20 inches behind the leading edge. ( that way we wont have to calculate the weight of the plane in our example.) if we add a passenger of 200 lbs. the moment arm would be -24 inches providing the passenger cg is 4 inches ahead of the leading edge. -24 X 200 -4800 inch pounds. assuming that we did not want to change the cg from the point we started at ( 20 ) we will ne a 4800 inch pound moment arm to counter. 4800 / 186 25.8 where 186 is the moment arm from the original 20 inch datum. leaving 25.8 pounds needed at the tail wheel. maybe this is too simplistic of an approach.... what think all? boyd summary datum at 20 inches behind leading edge moment weight moment arm 0 600 0 -24 200 -4800 186 25.8 4800 --------------------------------------------- 0 825.8 0 datum at leading edge (double checking the work) 20 600 12000 -4 200 -800 206 25.8 5314.8 --------------------------------------------- 19.998 825.8 16514.8 using the same weights added to the plane with the different datum line showes the cg at 19.998 inches which for all intent and pourposes the same as the 20 inch ( behind the leading edge) datum in the first example. this poses a question.... if by adding the weight on the tail it should eliminate the need for the horizontal to apply that force to keep the plane level.. would it or would it not create a clime performande penality? or would there be an increase due to decreased drag? puzzeled minds want to know. i end again boyd ________________________________ Message 17 ____________________________________ Time: 11:58:36 AM PST US From: CaptainRon Subject: Re: Kolb-List: Rod End Bearings and Fender Washers --> Kolb-List message posted by: CaptainRon Thanks for pointing that out.

The retaining bolt with a z bend on the end to secure it to the system always worried me. Quickly did a trade off for a small silencer of the conventional type that I still use today on the 912S. I believe John Bickham posted to the List his experience with the same set up on his MK III, 912. During our Kitty Hawk flight, the Super Trap Silencer, with all those discs and z bolt, nut and cap, departed the aircraft. We were over very inhospitable terrain at the time. John B was extremely lucky. He received damage to all three IVO blades and none to any other part of the aircraft. A very luck man indeed. Ask him if he wants another Super Trap on a pusher. Also, ask him what prop he is going to run on the 912.

They almost exclusively flew with a heavy 2 person load and with the 10+ pound tail wheel weight. I have flown a few hours in this configuration and it seems very stable. I take the weight off for solo. It feels great solo too. Even with the 10 pound extra in the tail, it feels perfect to use full elevator trim on takeoff. only 1/2 so to cruise and land. That seems right. It trims to hands off flight. I did just call TNK and they asked me to do a W&B and call them back because you shouldn't need a tail weight. I will be doing the W&B this weekend and will get back to them. I'll post my findings. I hope I can figure something simple like ailerons are drooped a little etc that is causing the nose heavy two person situation. I would love to ditch the tail weight.... just don't want to fly around pulling hard back on the stick w/ full trim to stay level. aaron - ----- Original Message ----- From: "boyd young" Subject: Kolb-List: weight and bal > --> Kolb-List message posted by: "boyd young" > > The previous two owners of my Kolb Mk3 always used a 10-15pound weight attached > (taped securely) to the tail wheel tube when flying dual.

However as you noted the > AC is not a requirement. I also have the large washers on > my rod ends, as the plans call for them. Ron Ron/John W/Denny R/Rick N/and the rest of you all: Just got back from Gantt International Airport. Did a thorough check of my aileron push/pull tube rod end bearings. The lower right showed a little wear. The lower left no wear. Both dry as bones. Failed to relube after I gunked the engine last week. Upper rod end bearings are inside a clevis, so, if they fail they will be kept in place. My aileron horns are one of a kind prototypes Brother Jim designed and fabricated in Feb 1991. I have decided to put washers on the bottom rod ends slightly larger than the bronze bushing. No need to risk a failure, even though chances are slim to none. As for flap p/p tube rod end bearings, I won't put washers on them. They are direct inline pull only. Get used once per landing. I don't think I need them there. Please, listen carefully. I am not recommending anything to anyone as far as AN970 fender washers go. If the plans call for them, they should be on there. What I say is not "gospel", simply sharing what I do or don't do, period. I don't have any authority to recommend anything to anyone. I am one member of the Kolb List among many. As far as I know, we have no rank structure on this List. Each and everyone is the same, whether a "newbie" to Kolbs or an "old fart". No one has to agree or disagree with me. I believe this is a discussion group, which means sometimes I can do the "devils advocate" thing. I can ask dumb questions, in an attempt to get some of you thinking on your own. I can have fun with the List. It eats up a lot of my time. With that, I think I will fly to Circle C, about 60 miles east of Gantt IAP. See if anyone has arrived for this weekend's flyin. Got to hurry though. It gets dark at 1700 now.

A web site with links to tested and suggested equipment and building hints for Kolb builders and flyers. Seriously, my son Jim (an IT guy) has categorized and archived Kolb-list messages from you and others to be contemplated now and accessed when needed. As the disassembled airplane story illustrated, it's much better to anticipate modifications, electronics and stall issues while building a MarkIII Extra with a Rotax 912S than to say OOPS! after it's covered and painted.

John Clayton (Jim's dad) -----Original Message----- From: owner-kolb-list-server@matronics.com [mailto:owner-kolb-list-server@matronics.com]On Behalf Of John Hauck Subject: Kolb-List: Warp Drive Props --> Kolb-List message posted by: John Hauck Morning Gang: Just got off the phone with Darrell at Warp Drive. He is the guy that is going to answer the phone when you call. He will be the one to recommend what prop to fly on your airplane. Warp Drive has come a long way since the days Dennis Souder shared with us, when Dennis would call Warp Drive and they would try to figure out what was going to work best on that particular application. They have the numbers now on most all applications, except some of the newer aircraft, and they will obtain figures for them ASAP. Warp has one of the best guarantees of the prop manufacturers - lifetime customer satisfaction. I called Darrell this morning to see if he would put white tips on my blades. Also to confirm the new polished prop hub will fit the 5" spinner. The last hub and spinner I got from them, the hub was slightly smaller than the spinner. This system did not work well in the pusher configuration. Now, that problem has been eliminated. Does the spinner improve performance in the pusher configuration? I don't know, but it does make the airplane look better. I got a chance to see the polished hub, spinner, and white tips at Oshkosh. They are an improvement on what I have now. With the new starter and slip clutch installed in my 912S, I anxiously await the arrival of my new prop. I flew the first 100 hours or so on the 912S with the 72" prop. It has been three years ago, but I still remember the kick in the butt those long blades made when I poured the coal to Miss P'fer.

Do you think the aileron droop/reflex makes a large enough impact on the nose high/low to adjust out my need for the tailweight? I know any answer is likely speculation until I get this W&B done.. but just curious how drastically adjusting the droop/reflex can change the nose heavy characteristic I am seeing.... damn I hope that when I get to the hanger and look at my ailerons and flaps that they are enough drooped to be causing the problem. That would be an easier fix than trying to move battery from behind seat to behind the tanks etc. Thanks for the input, aaron - ----- Original Message ----- From: "John Hauck" Subject: Re: Kolb-List: weight and bal > --> Kolb-List message posted by: John Hauck > > Aaron/All: > > I experimented with aileron droop and reflex until I got my > MK III to fly the way I wanted it to. > > When I droop the flaps the nose comes down.

Do you think the aileron > droop/reflex makes a large enough impact on the nose > high/low to adjust out my need for the tailweight? > aaron aaron/gang: I have found that the MK III is very susceptible to the high thrust line of a pusher configuration. My MK III requires a lot of nose up trim, especially if I have a passenger and a very light load of fuel, when the aircraft is a cruise power. If I pull the power back to idle or shut the engine off and glide, I do not need nose up trim. More like a little nose down trim. It is the nature of the beast. Yes, reflexing the flaps and ailerons will most definitely reduce the amount of nose up trim required during cruise flight. I attack this problem a little at a time until I get the aircraft rigged the way I want it. A couple turns of the rod end bearings (with big ass washers), then test fly to see if I have accomplished anything. I have flown my MK III with little tailwheels, the old Firestar snowmobile bogey wheel, and up to an 8" pneumatic Maule tailwheel. Doesn't really seem to bother my airplane one way or the other. I find my MK III, as well as Ultrastar, and Firestar, have extremely wide cg ranges. I, personally, have never had a cg problem on any of my Kolb airplanes, in just about any configuration. The other day a couple spins confirmed that. Feels like it is going over on its back, the nose is so low in a spin.

I am also planning on flying in summer with the doors off. ============================================ --- CRAIG M NELSON wrote: > --> Kolb-List message posted by: "CRAIG M NELSON" > > > > ----- Original Message ----- > From: CRAIG M NELSON > To: kolblist@matronics.com > Subject: rear windows > > I'm planning to put windows in the rear of my > MKIIIex.

Make up a spare set of doors that only come part way back and nothing behind them and you will have a great summer open cockpit airplane. Take a look at the top picture on this page, http://www.bcchapel.org/pages/0003/pg2.htm I flew to Oshkosh and back this way several years ago, plenty of air with out getting beat to death, good summer setup. I think the plans say that if you take the doors off, then you also better have all the rear enclosure off first.

Seeing how the air works on and around that rear stuff strikes me as that is a reeeally bad idea. My back windows come completely off in about 2 minutes. http://www.bcchapel.org/pages/0003/pg3.htm There is an aluminum u channel the runs along the bottom of each side window. The side windows are attached to the top surface window with piano hinge along either top edge, and at the front, they tuck behind a little Lexan flat piece which is permanent, it is in there just to make everything fit right. If I pull the piano hinge pins along the top of either side window, they come out in about 20 seconds and I drop them into the cargo space. Now I have an upper surface window in place, but the rear sides are open. This is for flying with the full size doors on in summer. I also have half length doors for the really hot days. At that point, I want the upper rear surface Lexan window gone also. The upper surface Lexan is attached to the back of the windshield Lexan with piano hinge, and at it's narrow lower back end with piano hinge, pull the pins, it is loose, leave it home. Or if you want to just lay it down, then just pull the front pin and it lays on top of the cargo area out of the wind. If you think it is worth the trouble, I can add a detailed page to the website detailing all the permutations. But not tonight...

Like a small bomb when the bolt lets go. No problem in the tractor config, but not good in the pusher config. You must have lots of problems with you exh system. I don't remember anything more than springs, fender washers, and bolts departing my 2 stroke exh and finding its way into and through my prop. The Super Trap has one bolt with a z bend holding it in place. When the bolt lets go, the whole kit and caboodle goes. For some reason, last time I changed the four springs that hold the silencer on my exhaust system, I saturated the springs with silicone seal from one end to the other. Especially the hooks. Couple days ago a spring broke right in the middle, but stayed in place. With all the goop I had on it, didn't have any other choice. Silicone seal is quick and easy compared to safety wire and does a better job for me. Take care, john h
